Why Does Your Tooth Hurt When You Drink Something Cold?
By Dr. Cohen — Mission Viejo, South Orange County Many patients here in Mission Viejo tell me the same thing:
“Every time I take a sip of cold water, I feel a sharp shock in my tooth.”
​
If this happens to you, it’s not something to ignore. Your teeth are sending you a message, and there are a few common reasons behind this sudden sensitivity.
​
​
A Cracked Tooth
A cracked tooth can expose the inner layers, making the tooth extremely sensitive to temperature changes.
This often happens when:
-
You previously had a large filling
-
You bit down on something unexpectedly hard, like a popcorn kernel
Even small cracks can create a sudden, sharp pain when cold liquid touches the tooth. Cracked teeth are one of the more common causes of cold sensitivity that I diagnose in the office.
​
​
​
A Dental Abscess
If the nerve inside a tooth becomes infected, you may feel sensitivity, pressure, or a lingering “shock” sensation.
An abscess is a more serious issue and should be evaluated promptly.
Patients often come in with cold sensitivity that turns out to be infection-related, so it’s important not to ignore ongoing symptoms.
​
​
​
Root Sensitivity
Sometimes the issue is simply exposed roots.
This can happen from gum recession or natural wear over time.
In some cases, this type of sensitivity is normal — and in others, it’s a sign that something needs attention.
​
What I Recommend
​
A good first step is to try an over-the-counter desensitizing toothpaste, such as Sensodyne. Many patients experience relief within a couple of weeks.
​
However, if the sensitivity persists, worsens, or is limited to a specific tooth, it’s essential to schedule an evaluation. That allows me to determine whether the cause is a crack, an abscess, or root-related sensitivity — and recommend the right treatment.
